“…Furthermore, root exudates from the plants with continuous cropping can stimulate the massive breeding of soil pathogenic microorganisms, leading to the imbalance of soil microflora (Hu et al, 2018). For example, succinic acid, p-hydroxybenzoic acid, p-coumaric acid, and glutamate in cucumber root exudates were found to be able to reduce the diversity index and change the structure of the soil bacterial community (Jin et al, 2019). In tobacco, members of the rhizosphere microbial community, such as Bacillus subtilis and Bacillus amylolyticus, increased significantly after the induction of plants with jasmonic acid (Zhalnina et al, 2018).…”

“…Continuous cropping obstacle is proposed to be the comprehensive effects of plant-soilmicrobe interactions (Standing et al, 2007;Inselsbacher et al, 2011). Excessive allelochemicals secreted by roots will stimulate massive population growth of pathogenic microorganisms in the soil, leading to an imbalance of soil microflora (Jin et al, 2019). In our previous study, we detected the dynamic change of the soil rhizosphere microbial community in continuous sugar beet cropping in Xinjiang Uygur Autonomous Region using 16S amplicon sequencing.…”

Sugar beet is vulnerable to years of continuous cropping, and allelopathy is one of the important factors leading to continuous cropping disorder. To explore the physiological and molecular mechanisms behind continuous cropping obstacles on sugar beet, this study combined transcriptomics and metabolomics to analyze the effects of different years of continuous cropping on metabolite changes, differential gene expression, and root exudate regulation in sugar beet. We collected sugar beet’s root samples from 1–, 3–, and 5-year continuous cropping systems for metabolome and transcriptome analyses. Our data revealed that T3 and T5 had 50 and 33 metabolites significantly different from T1, respectively. The autotoxic substance salicylaldehyde was found to continuously accumulate in root exudates with increasing years of continuous cropping. Sucrose was highly reduced in T3 (4.05-fold decrease) and T5 (2.01-fold decrease) compared to T1. Respectively, 2,660 and 3,515 differentially expressed genes (DEGs) were significantly regulated in T3 and T5 compared to T1. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses showed that metabolic pathways and biosynthesis of secondary metabolites were perturbed in T3 and T5 vs. T1. Integrated metabolomics analyses identified 73 DEGs involved in enriched metabolic pathways, all of which were the oxidation-reduction process pathways. In conclusion, this study provides evidence that continuous cropping obstacles can change the metabolome and transcriptome of sugar beet, affecting its growth and quality.
